Based the thermochemical equation below, which other equation shows the correct relationship between the chemical species and the enthalpy change? 3H2+N2⟶2NH3 ΔH=−96kJ A) 32H2+12N2⟶NH3 ΔH=−96kJ

B) 32H2+12N2⟶NH3 ΔH=+48kJ

C) 3H2+N2⟶2NH3 ΔH=+96kJ

D) NH3⟶32H2+12N2 ΔH=+48kJ

Base your answer on the information below and on your knowledge of chemistry. nitrogen dioxide, no2, is a dark brown gas that is used to make nitric acid and to bleach flour. nitrogen dioxide has a boiling point of 294 k at 101.3 kpa. in a rigid cylinder with a movable piston, nitrogen dioxide can be in equilibrium with colorless dinitrogen tetroxide, n2o4. this equilibrium is represented by the equation below. 2no2(g) n2o4(g) + 58kj at standard pressure, compare the strength of intermolecular forces in no2(g) to the strength of intermolecular forces in n2(g).
